Sorry about the problem you experienced.
Looks like lshttpd triggered a kernel bug.

Which version of linux and kernel are you using?
search the error message "Bad page state in process", I got many discussions about it in the kernel mailing list.
Only upgrade/downgrade to a kernel without this bug can fix this I think.

go over your thread at webhostingtalk, looks like you have been trying different kernel, since many people using RE5 stable kernel on their server, if it is a kernel bug with the stable kernel, a lot of users would report the same problem.

I recently took a trip so I was gone for about a week, which led to people leaving my host, however, the server managed to stay stable and was up for 5 days, till tonight which is about 24hrs later after I told everyone I was back and it looks like some clients came back over.

The script above works... just went 1 day with uptime, so I'll let it go for another day and see how it goes. if its still stable then I'm going to try a few things and narrow down the cause. I'll try removing drop_caches first and see what happens.

so far my ideas are:
- bad sector in memory?
- litespeed in some way caching which causes a corruption?

what i cant figure out is what im doing so different then all the other CPanel setups that run LS(default config) with probably more active sites then me. It could be a kernel issue as you pointed out... so I'll try upgrading to the latest and see what happens later this week.
